Troubleshooting; Electrical System Safety; Insufficient Water On The Brushes; The Machine Does Not Clean Well - COMAC Vispa 35E Use And Maintenance Manual

TROUBLESHOOTING

1. ELECTRICAL SYSTEM SAFETY

The machine is fitted with a thermal trip unit with manual reset.
The brush motor is reset by resetting the thermal trip unit located beneath the handlebars.
If the machine stops repeatedly in a short space of time, you must contact the Comac
technical assistance centre.

2. INSUFFICIENT WATER ON THE BRUSHES

1. Check the solution tank filter is clean.
2. Check the solenoid valve switch is on.
3. Check the quick connection is correctly inserted.
4. Check the cock regulation screws on the water outlet.
5. Check the vent pin on the solution tank cap is lowered.

3. THE MACHINE DOES NOT CLEAN WELL

1. Check the state of wear and tear of the brushes and, if necessary, replace them. The
brushes should be changed when the bristles are about 15mm long.

4. THE SQUEEGEE DOES NOT DRY PERFECTLY

1. Verify that the squeegee rubbers are clean.
2. Verify that the suction tubes are correctly inserted in their housing on the squeegee.
3. Verify that the distributor is clean.
4. Replace the rubbers, if worn.

5. EXCESSIVE FOAM PRODUCTION

Verify that a low foam detergent has been used. If necessary, add a small quantity of
antifoam liquid to the recovery tank.
Remember that, when the floor is not very dirty, more foam is generated. In this case the
detergent solution should be more diluted.
